In the variant of this production method known as wire EDM, the cutting is done with a thin brass wire and the fun combination of electricity and water. Wire EDM is what you use when you want to cut something that's, say, 300mm thick, and made out of a tough-to-machine metal.

Here's a GoPro view of mountain bike racer Dan Atherton, who broke his neck in 2010, riding down a treacherous mountain trail.

See firsthand what it's like to rip down one of the heaviest downhill mountain bike tracks ever created, through the GoPro view of the creator himself, Dan Atherton. It's why Red Bull Hardline is an event like no other. The long and technical course plays on a variety of disciplines, where incredibly steep and rocky technical sections were combined with a motocross run in and 50-foot gap jump to create one of the most progressive downhill courses on the planet.

Earlier this month, Henrik Moltke helped report the extent to which the massive, windowless, bombproof AT&T tower at 33 Thomas Street was implicated in illegal NSA surveillance of US and international communications, revealing that the tower was almost certainly the site referred to as TITANPOINTE in Snowden docs.

Alexander Unger is an animator and sculptor who makes excellent stop motion instructional videos (like this one on how to bounce things and this one on how to make things fly). Here's a recent claymation video he made, with great use of sound effects.

This is my first time ever working in Mozambique and I was on a jolly journey back home to South Africa.

I was crossing the border from Kruger National Park when I noticed a hippo on the bridge.
There were people walking around in the nearby vicinity so I automatically assumed this hippo was used to humans. I was quite fascinated by this so I took out my phone to start filming.

Suddenly the hippo turned and just started charging… I braced myself as I realized he wasn’t going to stop. He hit the bakkie head on and then tried biting it. I guess after that he decided he had won because he just turned around and left.

This was terrifying for me because I realized I had nowhere to go and no time to do it in. Beside me was a 50m drop so had he hit me on the side I have no doubt the car would have rolled down the embankment. Even though there was damage done to the bonnet of my vehicle and the door couldn’t open, I’m grateful there were no serious injuries at the end of day.

While employed at the Royal Canadian Mint, Leston Lawrence secreted 22 gold "pucks" into his rectum. He removed them and sold them for $165,000. He will be sentenced by Ontario Court Justice Peter Doody (yes, Doody).

Lawrence worked at the mint from July 2008 until March 2015. His job included purifying gold — jewelry, coins and bars purchased by the mint — by melting it, injecting it with chlorine gas and skimming off base metal until the molten gold was 99.5 per cent pure.

Once he believed the molten gold was pure, he was to scoop some out with a ladle, let it cool and then test it for purity. He was supposed to return the pucks into the vat of molten gold after testing.

Lawrence "clearly had the opportunity" to steal the gold because he often worked alone, and the security cameras would not have caught him slipping gold pucks into his pocket, Doody ruled. "His locker contained Vaseline and latex gloves, which could have been used to insert a puck into his rectum," he ruled, adding that there were no cameras in the locker room.

The Bank of England confirmed that its new £5 notes contain animal fat. “There is a trace of tallow in the polymer pellets used in the base substrate of the polymer £5 notes,” it tweeted yesterday. There's a petition underway to replace them with vegan currency.

The new £5 notes contain animal fat in the form of tallow. This is unacceptable to millions of vegans, vegetarians, Hindus, Sikhs, Jains and others in the U.K.

We demand that you cease to use animal products in the production of currency that we have to use.

The petition has 26,260 supporters so far.

Venezuela's currency is on track to inflate by 720 percent this year. Why? The drop in the price of oil hurt Venezuela's economy, and President Nicolás Maduro thought he could solve the problem by printing more money. It didn't work and now people are starving.

When the price of oil on the global market collapsed by two-thirds in 2014, Venezuela had little else to fall back on, so a natural reaction would have been for the bolívar to collapse. But Mr Maduro, who succeeded Hugo Chávez following the revolutionary leader's death in 2013, instead tried to control the exchange rate, creating a massive black market for currency.

Figuring out scams to get dollars and then sell them for bolívars became hugely lucrative business for Venezuelans, setting off a feedback loop that drove the inflation rate higher and higher.

In one of Caracas richer neighbourhoods, the owner of a tiny kiosk selling newspapers, cigarettes and snacks told the Washington Post that every evening he quietly stuffs a plastic bag full of the day’s earnings, around 100,000 bolívars (about £42) in notes of 10, 20, 50 and 100 bolívars. Venezuela has one of the highest crime rates in the world, and he said carrying that much cash frightens him.

Network Time Protocol is how the computers you depend on know what time it is (this is critical to network operations, cryptography, and many other critical functions); NTP software was, until recently, stored in a proprietary format on a computer that no one had the password for (and which had not been updated in a decade), and maintained almost entirely by one person.

You work at the college library. You’re in the middle of a quiet afternoon when suddenly, a shipment of 1,280 books arrives. The books are in a straight line, but they're all out of order, and the automatic sorting system is broken. How can you sort the books quickly? Chand John shows how, shedding light on how algorithms help librarians and search engines speedily sort information.
